It might be similar hardware (even identical) and the same OS, but it has a number of differences. The menus and core apps look different… easiest way is to look at the radio apps each unit uses. It also boots quicker and supports ODB2 and Torque out of the box.

It’s much more expensive too, but I guess you’re paying for the extra development and the stuff that works straight away. I personally don’t think it’s worth the extra and the accessories are extortionate, but it depends what you need it for. I paid well over half that price (€330) for a OUKU based unit with a Ford facia, built in DVB-T tuner and a canbus included. You can get a generic OUKU even cheaper than my unit. Maybe there is a cheaper supplier, but to buy just the DVB-T tuner (add-on module) and canbus from ekoore.com costs €300

It also has a different chassis at the rear… to the OUKU unit anyway :)

T-mobile will probably be blocking tethering. Have you used it successfully as a hotspot before?

Not sure if you’re asking how to get free internet or if you want to know how to use your phone/tablet as a hotspot, but there are loads of posts in this thread about problems and fixes to get it working.

Here is a simple guide:

I had to update my S2 then change it to “allow all devices” before it worked for me.

I would be just guessing if I tried to answer your question (was it a question?) about the analogue tv, but it’s probably best to left to someone that has one. Maybe you can explain what you mean by “do u work anolog tv”?

So I thought I would add my thoughts on my OUKU like unit I just received.

First things first, in true Chinese build quality fashion, my track fwd/back buttons are both identical (i.e. the arrows point in the same direction). But other than that it works OK.

I have rooted using Hal9k's software, I have also installed the module here (http://brady.thtech.net/) so my generic OBDII USB adapter should work (I'm still waiting for it to arrive to tell for sure).

I have install the following files: com.google.android.maps.xml, com.google.android.maps.jar from the CM7 GApps to their relevant folders.

I am able to install tasker with no problems, please note that you will have to go to their website to get the GB and earlier version.

I made a custom logo and install it to the correct folder in the system menu so it will be selectable even after setting a different one.

Lastly I ran the following commands from terminal emulator:

su
umount /cache
mount -o rw,remount -t rootfs rootfs /
rmdir /cache
mkdir /data/cache
ln -s /data/cache /cache

This will move the cache partition to the data partition, the in built cache partition is only about 30-35Mb this is where the Play Store stores the apk while it downloads, this is the reason larger apps (Angry Birds) fail when trying to download them, since the data partition is 1GB+ you wont run into this problem. I know there was a workaround already posted but this will survive a reboot and since the cache is only temporary it wont effect usable space on the data partition.

This should give you a rooted headunit where pretty much any compatible app (including Tasker and large apps) can be downloaded and installed, that will support cheap USB OBDII dongles and a permanent custom logo. The only missing item is push notifications for gmail, though you can add your gmail account to the standard email app and set a frequent refresh interval.

Lastly now tasker can be installed you should be able to kill the radio app on startup and choose a different app (i.e. Pandora) to be launched.

Also I found using ADW launcher with their 'action bar' and disabling the dock makes for a very tablet-esque ui I set the grid size to 9x4. ADW also offers a icon hack for using HDPI icons to make icons appear bigger on LDPI devices, problem is this doesn't seem to stick until you toggle this after a reboot, but they do look good (they are about the same size as the 4 big ones on the stock launcher).

Guys, I will go to Hong Kong soon and am considering to buy an Android head unit from there. I tried to read most of the thread but still have some questions.

I'm looking for a unit with a capacitive screen and hopefully pure Android 4.0 and good audio/FM quality. (It would be a huge bonus if it can be upgradeable later on) It should have minimal lag and dual zone(i.e. should play music or stream bluetooth call/music while navigating)

1- Could you recommend me any particular model? There are tons of these in Ebay but I can't be sure which one is good. An Ebay link or a photo would be great.

2- Is bluetooth available to Android in these pure models? Can I transfer files from my phone? Or can I use programs like Wifi Explorer?

3- Does anyone know where to buy these things in Hong Kong? (going to Shenzhen is out of option sadly)

4- Can I change which app loads at boot? (I would prefer the navigation come up)

5- Root is not top priority for me, but which models are rootable?

6- Which one has the best sound?

7- How can I tell if it is pure Android? I see on some listings that the system opens with 4 options, Android - Disc - Radio - BT. Does that mean it is Wince?

Thanks everyone in advance.

Can anyone recommend a USB port that works? The one I bought stops the Wifi Dongle from working correctly.
[Android Head-Units] Jake Bullit:
This is the one you want, I had problems with other hubs, so I bought this one from the states. Cost more but worth it

So I finally got around to test fitting this in my car. Everything went pretty well, steering wheel controls worked with just a single wire connection (no need for any adapter, i.e. SWI-PS), one of the 6 buttons doesn't register, but in reality the options for the buttons are pretty limited. I'm a little bummed that they don't work within Android apps, but I had read that going in and my primarily use will be for volume control or tuning the radio (I have widgets on the home screen for toggling my android music and primarily I just use Pandora which requires little input).

Another thing I noticed is that when launching an android media app, it kills the radio, even if that app doesn't play any music, for example Soundhound, so this makes it impossible to look up a radio song (Shazam and Play Sound Search don't seem to work). Again not a big deal, and definitely not something I banked on working, just would have been nice. Seems like there is definitely some underlying software/interface for the hardware inputs (radio tuner, disc, ipod input, etc), I would happily forgo the Ipod connection, Aux inputs, disc drive for a 100% only Android experience, but for what this is and how much I paid ($300) I'm happy. Sound quality is good (I have some bad alternator whine, but that was present on my Appradio2 also), the actual loudness and quality I believe is in fact a little better than the Pioneer.

I have tasker set up to launch Pandora once connected to Wifi, so within about 45 seconds from turning the key, I have Pandora streaming without having to touch a single thing, I know some people have complained about the the radio always starting but I haven't found that to be the case, though maybe that is because it isn't playing when I shut the car off.

Speaking of the radio, setting the presets was a little tricky since depending on when you press the preset button it will save certain RDS data (i.e. you can save a preset has a partial title to a song) but also the nice thing about that is you can also save them as the station name/id.

In summary, I am pleased with the unit, I bought it so I could have Pandora (with full control from the headunit), Google Maps Navigation, run Torque and control the radio without have exit the home screen and go to a different OS. It does all that and some for less than just about any other option, if you go into this think of it as a head unit with some enhanced features rather than a fully functional android device for your car you will be happy.

I have just ordered the S150 and an swc module and have a question. There is four wires from the S150 to connect to the module. One seems to be a 3.3 v cable from what I can see in the wiring diagram. What is it needed for? Someone only connected one wire and it worked anyway. Isn't allwas all of the wires needed?
[Android Head-Units] jakejm79:
It depends on your car, older cars use multiple resistors in series and certain ones are activated (for want of a better term) when you press a button, i.e. pressing vol+ will show 200 Ohms between ground and the +ve wire to the steering wheel controls, vol- will show 400 Ohms, etc. If your car is like this then all you have to do is connect that +ve feed wire to the the steering wheel control wire 1 on the head unit and use the inbuilt menu to program the buttons (some cars wont use resistance between +ve feed and ground but another reference, in which case you would need to connect two wires). New cars have the steering wheel controls connected via can bus so when a button is pressed a data packet is sent and not a specific resistance, these android head units can't understand that data on their steering wheel input feeds so you need to use an adapter to convert that data packet to a standard resistance reading.

An adapter is pretty much always needed regardless of your steering wheel control type with standard aftermarket radios since they don't have a menu to customize the buttons so you need an adapter to take car of this and send the correct generic signal for the action you want when a button is pressed.

Anyway research your car and find out how it handles the steering wheel controls and then you can tell if you need an adapter or not.

Gmail Push Notifications

So I got push notifications working for Gmail.

Download Synker from the Play Store.

Open it up, hit the 2nd option (Accounts & Sync Inspector), now here is were it gets difficult, quickly scroll down to the Gmail option (on mine it was the 2nd one, 1st one was FB). Tap it then check the box that says "Auto Sync". If you aren't quick enough you will get the warning about purchasing the key, but if you are quick you should have time to enable auto sync before the warning comes up. Now you should get push notifications for Gmail and not have to manually refresh.

I've tested it a little and it isn't as fast as on my phone, but they do pop up without having to refresh.

Also all my purchased apps from other devices seem to now show up as purchased (I don't believe they did before) so I can easily install them without having to side load them.
[Android Head-Units] blue swede:
The car needs an adapter, allready ordered one. On the wiring diagram of my car (see below) there are two leads (12 and 13) for the swc. The module comes wired to the correct connector for my car but with a universal connector from the module to the stereo (I guess with loose wires). I'm not sure if I need to connect the "ACC - 3.3v" wire to the module. What purpose does that cable have? It looks like the module gets the power from the leads of the car specific plug (both 12v positive and ground). (also below)

Navigation app audio issues

For those having audio issues with GPS app replacements - try making sure that the Navi button is set to the app as well. On my unit at least (a T7019a) it causes the audio of whatever app is selected to be correctly routed/mixed.
[Android Head-Units] jakejm79:
I suspect you can probably just connect the one loose signal wire to the Key 1 wire on the head unit, but without specific information about the adapter I don't know. Doesn't the adapter have instructions on how to hook it up to an aftermarket stereo?

Freedompop Bolt 4G stick

Just purchased a i802 variant with custom faceplate for VW Touareg direct from China via AliExpress:

CompuCN Model# CN-I042

Love the unit so far. It is running Android 2.3.4 and I think is identical to the RoadNav S150. I have not however been able to get my FreedomPop Bolt 4G stick to work with the unit. Was wondering if anyone else has had any success. I can't even get the device to show up running netcfg from terminal. (was able to root unit with Framaroot without difficulty).

Also wondering if there has been any success in upgrading android version on the unit/custom rom development .

GPS location fix problem

Hello,

I ordered this unit from ebay ("Android 6.2" Double Din 3G-Wifi Car GPS Nav DVD Player BT Indash Radio+CAMERA") and after installing this unit, I am not getting any GPS signal. The location icon on the status bar always blinking and in Sygic, it always says "waiting for GPS signal". I replace the GPS antenna with a new one and the same issue with the new antenna. Please help.

Thank You

[Android Head-Units] blue swede:
The module came with the mail yesterday and yes, there is a wiring diagram included. I don't think it will be any problem fitting the module.

I also got my S150 unit yesterday and it seemed to work fine until I inserted a micro SD card in the slot (not the gps slot). The unit didn't react at all. I tried three different cards, all working in the usb port at the back and in the gps slot. Now I probably will have to send it back to Hong Kong. The great deal I got from the seller doesn't seem to be so great any longer. Has anybody had this problem with the micro SD card reader? If there is a solution I would be more than happy!
[Android Head-Units] Saxerud:
I assume you have tried the little reset-button? If the S150 has one, I have the Ouku type, so I'm not sure about the S150. You will not loose any data by pressing it. :good:
[Android Head-Units] blue swede:
Yes I have. Didn't make any difference...
[Android Head-Units] madamko:
you did on the SD cards folder Music ( i.e. mp3 files) and folder Video ( i.e. avi)? - Partition Fat32
[Android Head-Units] adit9989:
On the BT (phone) menu dial #*98723

---------- Post added at 08:41 AM ---------- Previous post was at 08:32 AM ----------

What capacity is the card ? Try first with something 32 GB or less.(64 GB will work if you format the card as FAT32- exFAT is not supported).

Install ES file explorer and try the card in the "sdnavi" slot (the GPS one). If you can access there put it back and see if you can see it on the other slot. If works in one, probably the controller is OK but you have a bad slot (not that it makes any difference).

Try reset to factory defaults (or something like this) in settings. This will format the internal partition and reinstall all the applications. Reboot the unit. Normally when booting with an SD card installed you will see a notification about mounting the SD after boot, it takes 1-2 seconds to do this. If still does not work, you have a defective unit (hardware) nothing more you can do, most likely.
[Android Head-Units] blue swede:
I have reseted the unit several times but that don't help. I have recorded a video that shows what happens (or don't happens) with the different cards. I have one 2gb card formated with FAT32, one 2gb card that I don't know how it is formated and one 8gb card. The unit recognizes all cards in the gps slot and with the usb cable but not in the "meda" slot. I have posted the video link to Hifimax but I'll have to wait until tomorrow for them to reply.

http://www.youtube.com/watch?v=WSrmZBNJIa4&feature=youtu.be

It's hard to see, but about 0:50 in the video I put in the sd card in the gps slot. That's what the unit recognizes, not the media slot.
[Android Head-Units] adit9989:
Yes, it looks like your slot is defective. You "could" use sdnavi only but is inconvenient as many app will not recognize it and also internal players will not show it. Get the unit exchanged if you can.

Has anyone figured out how to mirror to rear monitor ?

Or even play a movie (thru an app not thru dvd) and have it show on the rear monitor ?
[Android Head-Units] blue swede:
I assume Hifimax will exchange my unit. If I want to root or upgrade I need to have access to the sd card I guess. I think I need to root my device since I can't install several apps through google play. Read somewhere that rooting would solve that. Spotify for example is one of the apps that doesn't install. Swiftkey keyboard use the sd card for storing language packs etc. I really need the sd card slot...
[Android Head-Units] adit9989:
Yes try to exchange the unit, you paid for it. Rooting itself will not solve the problem, but gives you access to some way of spoofing the device. Many applications are set as "incompatible" on market, side loading may work for the free ones but I have a few I paid for it and they don't work properly if I side load them (license check). I played a little bit tried Market helper but did not work, was thinking to try to edit build.prop but I am a little bit reluctant to play with this as I don't have a recovery, like on a tablet. The factory reset appears not to do a full wipe, it reinstalls the apps but for example I did not loose the root after. If you manage to spoof your device and it works please post the method you use. (there is an build.prop editor on google play you may want to try it may simplify editing). For now I manage to side load some apps I needed so I'm waiting for somebody to confirm a working spoofing method before I play with it.
[Android Head-Units] blue swede:
I'm still waiting for the respond from Hifimax. Hopefully tomorrow. They are 7 hours ahead of my local time so hopefully they have left an answer tomorrow morning when I wake up... :)

If and when the problem is solved I will root my device. As far as I understand I have to use Framaroot to do this (S150 model). I will get back for some help when it's time! :o
[Android Head-Units] adit9989:
Yes Framaroot works. Good luck exchanging the unit.

Hello,

Anyone ever faced this prolem on this unit? Please help me. I am getting a hard time to get this unit replaced with the seller.

Thank you
[Android Head-Units] adit9989:
Did you connect the GPS antenna ? Did you try to move it out on top of the car ? On most cars will work inside the dash but very few have some GPS signal blocking on windows (does your phone GPS work inside the car ?)

Also you should have a build in app for monitoring the GPS on your unit. Also you can download GPS test from market. Make sure the GPS is enabled in android settings (locations). If none of this works probably you have a defective unit.

Your unit is an OUKU (Freescale CPU) probably maybe somebody who has one can give you more details, what I told you are general things to check.
[Android Head-Units] syswhiz:
Thanks for the reply. Yes I have connected the GPS antenna to the unit, placed the antenna on the roof of the car, the funniest part is I was driving around the streets and parked my car under open sky for hours to get the GPS signal, nothing worked. Then I ordered a new GPS Antenna, connected to the unit, still this did not work. I installed "GPS Test" and could see the similar message in this application as well, "searching for GPS signal". I also verified in the settings, GPS is enabled under locations. I could see the location icon always blinking on the status bar (on the top right corner of teh screen, near the time icon). Generally in my cellphone, it blinks and goes off once the satellites are locked, but here in this unit, I never saw it to be steady and gone off.

On the back of the GPS antenna (I could see on both the GPS antennas I have now) I could see it is written, the power requirement is 3V to 5 V. I am wondering, how this antenna is getting the power from the unit? Is is getting on the same wire which is connected to teh unit and suppose to send the GPS signal to the unit? Also do I need to ground the unit by connecting the body of the unit to the car body?

Any other info I can try on the unit to make the GPS work? Anyone else faced similar situation on these devices?

Thank You.

[Android Head-Units] tin2001:
That's normal for GPS antennas... Most require power. And yes, they get their power over the same wires as the signal... It's quite a common setup in a number of industries, not just GPS receivers.

Satellite TV receivers do a similar thing to power the LNB (the knobby thing no the dish). Some terrestrial TV masthead amplifiers also accept power input over the signal output line. It's just a convenient method to supply power over a cable you're going to have to run anyway.

Edit: As for the problem of it not working... Is it just struggling to find satellites? Got GPSTest or some similar app installed that can show more detailed info about the GPS status?

tmobile tethering issue

T-mobile will probably be blocking tethering. Have you used it successfully as a hotspot before?

i'v used the phones hotspot on other devices and have been able to connect and surf on the other devices but not the stereo.while connected to my home wifi the stereo works fine, connects and surfs. I even went to the tmobile store and connected through through one of the hotspots(data only device) and that allowed me to surf. only when the stereo connects to my phone does it not work. Tmobile keep pushing me to the manufacture of the phone or the stereo. they have told be that there is a restriction with the stereos wifi connection. i just cant figure out why this wont work.

android 4.0 double din chinease, bluetooth question

Hi,

I know this thread is about the "pure android device", but for forum policy Im not allowed to post to developers forum, so I'll try here anyway...

Ive got a chinease double din unit, the one with wince+android 4.0.0.

On the contrary to what others seem to think, this unit does run android not as a task in CE.

Ive manage to compile a bluetooth driver for my unit and load it, I can do a hcitool scan, hciconfig hci0 etc. and the dongle seems to work

Now to the question: Im unable to set bluetooth to On in the droid gui, so no apps can see the bluetooth device.

What else does android require to use bluetooth ?, I assume the stock rom has some sort of basic support for bt, since the hcitools are there.

Do I need to start some sort of bluetooth service ? (thinking about dbus, and bluetoothd now). Also where should one place the driver in the filesystem, /lib/modules/ seems to be one place, but /system/lib seems to be the place on my samsung phone?

BR

Regarding the device, my qualified guess is that the screen has multiple video inputs, one directed towards CE and one towards android...
